Shielding Effect of Aluminum Against Cs-137 Source, According to Gamma Ray Transmission Technique

Journal of Engineering Technology and Applied Sciences, 2022
In this study the shielding effect of the Aluminum element against radiation is referred to by using the gamma ray transmission technique. Selected gamma-ray source Cesium is monoenergytic and not necessary the activity correction due to its half-life. Absorption caused by aluminum leads to a reduction in the radiation dose exposed. In the literature,

Study of Gamma-ray Shielding of Two Different Heavy Metals and their Combination for Cs-137 and Co-60 Sources

Engineering, Technology & Applied Science Research, 2023
This article presents data collected by measurements of lead (Pb) and iron (Fe) and their combination as heavy shielding materials. Measurements were performed using gamma photon energies of 662, 1173, and 1332keV for the Cs-137 and Co-60 sources. The theoretical data part was calculated using WinXCom, Phy-X, and Py-MLUBF software packages.

Modelling and Monte Carlo organ dose calculations for workers walking on ground contaminated with Cs-137 and Co-60 gamma sources [PDF]

Radiation Protection Dosimetry, 2010
A pair of walking phantoms was developed from deformable mesh phantoms to represent individuals walking on contaminated ground. The Monte Carlo N-particle extended version code was used to calculate organ doses from ground contamination scenarios involving parallel and isotropic planar sources of Cs-137 and Co-60 with concentrations of 30 kBqm(-2). For

Radiation damage and recovery properties of common plastics PEN (Polyethylene Naphthalate) and PET (Polyethylene Terephthalate) using a¹³⁷Cs gamma ray source up to 1.4 Mrad and 14 Mrad [PDF]

Journal of Instrumentation, 2016
Polyethylene naphthalate (PEN) and polyethylene teraphthalate (PET) are cheap and common polyester plastics used throughout the world in the manufacturing of bottled drinks, containers for foodstuffs, and fibers used in clothing. These plastics are also known organic scintillators with very good scintillation properties. As particle physics experiments

Investigation of Behaviour of Titanium Diboride Reinforced Boron Carbide-Silicon Carbide Composites against Cs-137 Gamma Radioisotope Source by Using Gamma Transmission Technique

Acta Physica Polonica A, 2012
Boron carbide is a material which has wide application areas in industry including nuclear technology. Titanium diboride reinforced boron carbide‐silicon carbide composites were studied for searching of the behaviour against the gamma ray. It has been adopted that depending on their properties such improved materials can be used in nuclear technology ...
